Glasgow: The University of Glasgow said on Wednesday that several buildings on its campus, including a mailroom, had been evacuated "as a precautionary measure" and would remain closed all day.
Police in Scotland said suspicious packages were found at the university and a bank building, a day after three London transit hubs received letter bombs.

The force said that so far there is nothing to link the incidents.
It's unclear if the packages are connected to incidents Tuesday in which three small explosive devices in plastic mailing bags arrived at offices for two London airports and a train station.
One of the envelopes, sent to Heathrow Airport, partly caught fire but no one was injured.
